I am reading the linear algebra book “Google’s PageRank and Beyond – The Science of Search Engine Rankings” by Amy N. Langville & Carl D. Meyer on the math behind Google’s search engine.

In Chapter 4 the PageRank equation is presented.

$\pi^T = \pi^T ( \alpha S + ( 1 – \alpha ) E )$

Google PageRank.
